This is the first time I’ve seen this video. As to how to respond ? The threat is being dealt with by PD, attempting to utilize a legal gun would only add more confusion to the scene with the strong potentially of PD seeing you as a threat also. IMHO the correct response is to take cover, assist others if needed with taking cover and provide basic fist aide if needed.
Fist Responders EMT get a total of six months of training and then need to pass a state or national test to be a certified Emergency Medical Technician. Their understanding of scene safety no matter how hard the Instructor drills them on it will come from experience. To become a Paramedic it takes another 12 months of Didactic class room learning along with a minimum of 160 hrs clinical (Hospital) and a minimum of 480 hrs of field Internship followed by a state or national test to become a licensed EMT-P. Scene safety is usually more important at this level but what isn’t taught is scene safety for the OD or ALOC. As a young Medic or EMT any where from 18 to 24 years of age you focus on the adrenalin rush of the save. This can lead to some tough street medicine lessons. As you get older and gain more experience as a First Responder the importance of weapon checks become an important part of scene safety and scene control on all calls. Todays standard in many locations in California for a violent scene and a OD qualifies as a violent scene, theFire Department and Ambulance service are required by protocol to wait for PD to clear the scene first.
I’ve never been an Ambulance driver, but I have been a Paramedic sense 1992 and utilized and ambulance for more than 25years to provide medical treatment in the field and transportation to an ER.
